It poured cold water on a scenario sketched by the IPCC – that to restrict temperature rise to 2.4C, CO2 emissions would have to peak by 2015 at the latest and then fall between 50 and 85 percent by 2050.
.....
But the 2007 edition of the IEA's World Energy Outlook saw no peak in emissions before 2020.
.....
To achieve the 450ppm target would mean that CO2 from energy sources would have to peak by 2012, and this would require a massive drive in energy efficiency and switch to non-fossil fuels, the report said.
In a massive report issued this year, the IPCC said that since 1900, the mean global atmospheric temperature had risen by 0.8 C (1.44 F) and levels of CO2, which account for about three-quarters of greenhouse-gas output, are now at their highest in 650,000 years.
By 2100, global average surface temperatures could rise by between 1.1 C (1.98 F) and 6.4 C (11.52 F) compared to 1980-99 levels, the IPCC said.

BRACEWELL: Using a broad brush, all climate change indicators are ahead of their predicted schedule. Some are ahead of worst-case projections.
.....
Also, how many expect India and China to significantly reduce their GHG emissions (while Canada, US Aus and EU refuse)?
.....
A global recession (as seems imminent) would alter many of these predictions.
